Next to my previous article devoted to programming MMDVM firmware on an Arduino Due board<\/a>, here is the step-by-step presentation of programming MMDVM on a STM32F4xx board.<\/p>\n

La platine STM32F4xx du constructeur ST Micro electronic<\/a>\u00a0permet avantageusement de remplacer l’Arduino Due dans son application de relais num\u00e9rique multimode MMDVM<\/strong>. De plus la\u00a0platine STM32F446RE Nucleo <\/a>\u00a0 par exemple est accessible \u00e0 un prix plut\u00f4t bas (environ 15\u20ac)<\/p>\n

The STM32F4xx board of the manufacturer ST Micro electronic advantageously allows to replace the Arduino Due in its application of multimode digital MMDVM repeater . Moreover the STM32F446RE Nucleo for example is accessible at a rather low price (about 15 \u20ac)<\/p>\n

Download MMDVM<\/h2>\n
    \n
  1. The firmware (software) of MMDVM must be download on\u00a0github<\/a>\u00a0platform.
    \n    https:\/\/github.com\/g4klx\/MMDVM<\/a><\/li>\n
  2. Download the ZIP file\u00a0from the top right button
    \n\"\"<\/li>\n
  3. Unzip\u00a0MMDVM-master.zip<\/em>\u00a0file in a directory.<\/li>\n
  4. Rename the directory to \u00a0MMDVM<\/em><\/li>\n
  5. Open the configuration file “Config.h” to match to my MMDVM filtering shield<\/a>:\n
      \n
    1. Validate the 12 MHz external oscillator\n
      #define EXTERNAL_OSC 12000000)\r\n<\/pre>\n<\/li>\n
    2. Indicate the version of the MMDVM\u00a0board\n
      #define ARDUINO_DUE_NTH<\/pre>\n<\/li>\n
    3. Inform the network of the signal level measured by the receiver\n
      #define SEND_RSSI_DATA<\/pre>\n<\/li>\n
    4. Validate pin assignment to install a Nextion touch screen\n
      #define SERIAL_REPEATER<\/pre>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
